Turbo Assembler (TASM) is a computer assembler (software for program development) developed by Borland which runs on and produces code for 16- or 32-bit x86 DOS or Microsoft Windows. It can be used with Borland's high-level language compilers, such as Turbo Pascal, Turbo Basic, Turbo C and Turbo C++. The Turbo Assembler package is bundled with the Turbo Linker, and is interoperable with the Turbo Debugger. TASM can assemble Microsoft Macro Assembler (MASM) source using its MASM mode and has an ideal mode with a few enhancements. Object-Oriented programming has been supported since version 3.0. The last version of Turbo Assembler is 5.4, with files dated 1996 and patches up to 2010; it is still supplied with Delphi and C++Builder.

TASM itself is a 16-bit program; it will run on 16- and 32-bit versions of Windows, and produce code for the same versions. There are ways to run 16-bit programs such as TASM on 64-bit Windows (e.g., on a virtual machine), but it will not generate 64-bit Windows code.
The Borland Turbo Assembler 5.0 package is supplied on three 3.5-inch diskettes and with three small books.
